This research investigates the role of entrepreneurial leadership in micro-enterprise development in the district of Majalengka in West Java, Indonesia. This study applied a qualitative content analysis method to understand the phenomenon of micro-enterprises comprehensively. The data of this research was collected using surveys, interviews, and a group discussion. The findings indicated that technological information adaptation plays a crucial role in the development of micro-enterprise development. Since the group of millennials dominated the leadership, it has provided more creativity by implementing technological information instead of the previous generation that faced difficulties in adopting the technology. This study noted that inadequate technology adaptation makes micro-business gradually lose customers, and the business was threatened to close. Meanwhile, the role of leadership drives the business development, sales have risen, the number of products has been increasingly diverse, and business capital and number of employees have grown. The establishment of an entrepreneur group could facilitate peer-to-peer contact, knowledge transfer, training, and intervention to enhance leadership and business development. This finding pointed out that the leadership will successfully influence business development when supported by several characteristics such as manage the business, capture opportunities, confidence, firmness, personal integrity, communication, and social and technical expertise.

According to the decrease in birth rate and reduction of population, many schools in rural area have brought about the r decrease of number of student, and environment of education have became deteriorated. Accordingly, small schools be required improvement, and it should be altered placement of schools because it change number of student, distance and time of attending school, and formation of school zone are changed by alternating of human and physical environment. Merger and abolition of small schools are inevitable for change of placement standard to school and qualitative improvement of environment of education in rural area. This study researches the user's satisfaction at the boarding middle school following the merge and abolition of small schools in rural area. Finally, it reports the results of satisfaction research: the users are generally satisfied with education and student school life in the unified dormitory school.

Radicalisation has become an important issue for the Kyrgyz Republic with an increasing number of individuals leaving the country for conflict zones. The government of the Kyrgyz Republic adopted a number of policies to prevent radicalisation and violent extremism among youth. One of these measures is piloting a new subject, titled, History of Religious Culture, (История религиозной культуры) in public schools. The analysis in this paper aims to explore the experiences of teachers, who have taught the new class. The article also examines any differences in the level of resilience of pupils in schools, piloting and not piloting the new subject, towards radicalisation and violent extremism. Data used in this article comes from a survey with 760 adolescents across public schools in six regions of the country and key informant interviews with teachers who have taught the new class. Qualitative findings showed a positive experience of teachers who reported expanding their pupils' and their own knowledge of various religions. Quantitative findings indicate that the new class, History of Religious Culture, may have had a positive impact on violence-related beliefs in pilot schools that reported views less supportive of violence. The study concludes that the government's response to radicalisation and violent extremism has expanded beyond a security approach by including education. This, however, poses a risk of securitising education.

The aim of this paper is to review the current knowledge management (KM) practices and their importance in the public sector of Saudi Arabia. Using the term "knowledge management in public sector", a search for available works was done in Google Scholar. In the first stage, the search for literature published under anytime choice was done in the first 10 pages of the search engine. Then another nine pages of Goggle Scholar were searched for more recent works published setting the time as 2014 to 2018. The search yielded 37 usable works for this review. The results of this literature search and review indicated that out of the 37 works reviewed, only three works were related to Saudi Arabia. Number of papers on factors of KM were maximum, many of them giving diagrammatic presentation of their results. KM modelling itself is not easy as only very few papers on KM modelling were available. Problems of too much reliance on qualitative data and hypotheses not matching with the literature backgrounds for them were also found. Considering the works related to KM, the number of papers in various categories may indicate the dimensions of KM to be considered when KM is implemented or evaluated in any public sector of any country. This applies to Saudi Arabian public sector organizations also. There is a fertile ground of research waiting to be investigated by researchers in Saudi Arabia.

Construction accidents are difficult to prevent because several different types of activities occur simultaneously. The current method of accident analysis only indicates the number of occurrences for one or two variables and accidents have not reduced as a result of safety measures that focus solely on individual variables. Even if accident data is analyzed to establish appropriate safety measures, it is difficult to derive significant results due to a large number of data variables, elements, and qualitative records. In this study, in order to simplify the analysis and approach this complex problem logically, data preprocessing techniques, such as latent class cluster analysis (LCCA) and predictor importance were used to discover the most influential variables. Finally, the correlation was analyzed using an alluvial flow diagram consisting of seven variables and fourteen elements based on accident data. The alluvial diagram analysis using reduced variables and elements enabled the identification of accident trends into four categories. The findings of this study demonstrate that complex and diverse construction accident data can yield relevant analysis results, assisting in the prevention of accidents.

Most existing low-light enhancement algorithms either use a large number of training parameters or lack generalization to real-world scenarios. This paper presents a novel lightweight and robust pixel-wise polynomial approximation-based deep network for low-light image enhancement. For mapping the low-light image to the enhanced image, pixel-wise higher-order polynomials are employed. A deep convolution network is used to estimate the coefficients of these higher-order polynomials. The proposed network uses multiple branches to estimate pixel values based on different receptive fields. With a smaller receptive field, the first branch enhanced local features, the second and third branches focused on medium-level features, and the last branch enhanced global features. The low-light image is downsampled by the factor of 2b-1 (b is the branch number) and fed as input to each branch. After combining the outputs of each branch, the final enhanced image is obtained. A comprehensive evaluation of our proposed network on six publicly available no-reference test datasets shows that it outperforms state-of-the-art methods on both quantitative and qualitative measures.

The purpose of this study establishes the deep neural network (DNN) and Decoder models to predict the flow and thermal fields of three-dimensional wavy wings as a passive flow control. The wide ranges of the wavy geometric parameters of wave amplitude and wave number are considered for the various the angles of attack and the aspect ratios of a wing. The huge dataset for training and test of the deep learning models are generated using computational fluid dynamics (CFD). The DNN and Decoder models exhibit quantitatively accurate predictions for aerodynamic coefficients and Nusselt numbers, also qualitative pressure, limiting streamlines, and Nusselt number distributions on the surface. Particularly, Decoder model regenerates the important flow features of tiny vortices in the valleys, which makes a delay of the stall. Also, the spiral vortical formation is realized by the Decoder model, which enhances the lift.

간 역동적 CT(Liver Dynamic Computed Tomography; LDCT) 검사에서 일반적으로 사용하는 프로토콜과 관전압을 낮게 설정한 후 프로토콜을 변화시켰을 때 방사선량과 영상의 질을 비교하여 영상의 질을 유지하면서 방사선량을 감소시킬 수 있는 방안을 알아보고자 하였다. LDCT를 시행한 환자 중 신체질량지수(body mass index; BMI)가 18.5~24인 환자 40명을 대상으로 일반적인 복부 CT 검사 프로토콜을 적용한 A그룹 20명(관전압: 120 kVp, SAFIRE strength1)과 관전압을 낮게 설정한 B그룹 20명(관전압: 100 kVp, SAFIRE strength 0~5 적용)이었다. 영상의 질 평가는 동맥기의 간 실질 조직, 대동맥, 상장간막동맥, 복강동맥, 내장지방 그리고 백그라운드에 관심영역(region of interest; ROI)을 설정해 잡음(noise), 신호대 잡음비(signal to noise ratio; SNR), 대조도 대 잡음비(contrast to noise ratio; CNR), CT number를 측정 비교하였다. 또한 정성적 평가는 경험이 풍부한 영상의학과 전문의 2명이 0~3점까지로 평가하였다. 방사선량은 총 DLP(dose length product)와 유효선량, CTDIvol(volume computed tomography dose index)을 비교하였다. 관전압 100 kVp에서 SAFIRE가 높을수록 잡음은 감소하고, CT number는 증가하였다. 따라서 SNR과 CNR은 SAFIRE 단계가 높을수록 증가하였다. 관전압 120 kVp와 비교하여 잡음, SNR, CNR이 SAFIRE strength 2, 3에서 가장 유사하였다. 정성적 평가는 SAFIRE strength 2가 가장 많았고 관전압이 100 kVp일 때 영상의 질이 더 좋다고 평가한 경우는 SAFIRE 1이었다. 방사선량은 120 kVp에 비해 100 kVp에서 21.69% 감소하였다. BMI가 비교적 높지 않은 LDCT 검사의 경우 공장에서 출고될 당시에 관전압이 높게 설정되어 있어 불필요한 방사선피폭이 우려되고 있는 현실을 고려하면, 본 연구 결과에 따라 관전압을 낮게 설정하고 SAFIRE strength를 2로 조정하면 영상의 질 저하 없이 방사선량도 감소시킬 수 있을 것으로 사료된다.
